If c = map(sum, zip([1, 2, 3], [4, 5, 6]))
c Out[7]: [5, 7, 9] why then can't I do this? a = ([1, 2], [3, 4]) b = ([5, 6], [7, 8]) c = map(sum, zip(a, b)) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-3-cc046c85514b> in <module>() ----> 1 c = map(sum, zip(a, b)) TypeError: unsupported operand type(s) for +: 'int' and 'list' How can I do this legally?
